With rapid growth of the internet, need for the mobile communication networks is increasing. In this paper, we implement and test Mobile IP Protocol in Embedded System. Our Mobile IP-based testbed consisted of two sub-networks and each sub-network was configured to operate independently through use of router. To satisfy integrated wired/wireless network model established on the testbed design and show generality of the testbed, we implemented mobile nodes, home agent, foreign agent and router on the basis of Linux operating system. As the results of the evaluation, we confirmed that mobile nodes operated properly according to Mobile IP Protocol.

The developmental processes of eosinophilic granule formation were ultrastructural investigation of eosinophilic granulopoiesis in 15 cases of human fetal livers from 8 to 34 weeks of gestation. 1) Numerous vesicles, microgranules and small agranular and granular vacuoles were distributed around the distended Golgi apparatus in myeloblast and eosinophilic promyelocyte. 2) Granular matrix of vacuoles contained small granular vacuoles, serveral vesicles and mutilamellar structures. The granular substance exhibited higher electron density than that of cystic rough endoplasmic reticulum(RER) and was similar partly to that of immature eosinophilic granules. 3) Distended cystic RER was fused to produce matrix of maturing granules with granular vacuoles and immature eosinophilic granules. 4) Immature eosinophilic granule which began to be produced in eosinophilic promyelocyte, had myelin sheath-like structure and debris of vesicles and granular vacuoles and those disappeared immediately. The charicteristic crystalloid inclusions began to develop in immature eosinophilic granule of myelocyte. In summary, it is suggested that vesicles and granular vacuoles as well as RER in the myelocyte and promyelcyte are participating in the formation of immature eosinophilic granules which become mature with the appearance of charicteristic crystalloid inclusion

Twelve-year-old, catrated male, weighting 8 kg, Miniature Schnauzer dog was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with history of depression. Result of blood analysis revealed anemia, thrombocytopenia, azotemia, elevated ALP, ALT and CK. On the radiographic examination, splenomegaly and loss of abdominal serosal detail were observed. Abdominal ultrasonography showed rounded mass of spleen and liver, ascites were observed. Splenectomy was performed and found that splentic tail had been ruptured and two samples from nodules on liver were obtained for histopathology. The result of biopsy revealed that hemangiosarcoma of spleen metastasized to the liver. Carboplatin was chosen as the patient had congestive heart failture. During chemotherapy hemangiosarcoma was metastasized into peritoneum and abdominal cavity. Intraperitoneal chemotherapy was preceded at this moment. After 99 days of initial visit, patient was euthanized due to severe anemia and thrombocytopenia.

We have investigated the effect of the pulse aspect(pulse ratio and frequency) on the characteristics of the nitriding layer in the micro-pulsed plasma nitrided SCM435 Steels. Properties of the nitrided layer were analysed by using optical microscope, scanning electron microscope(SEM), X-ray diffractometer(XRD) and micro-Vickers hardness tester. It was found that both the compound layer thickness and the surface hardness decreased with decreasing of pulse ratios. At high pulse ratio, the compound layer thickness and the surface hardness were rapidly decreased with decreasing frequency compared to lower pulse ratios.

기내배양과 자연조건에서의 유자(Citrus junos Sieb. et Tanaka)의 부정배 발생의 특징

송원섭,진영욱,김동철,우 서 順天大學校 1997 論文集 Vol.16 No.1

유자(Citrus junos)의 부정배는 자연조건에서는 주심조직과 배낭근처에서 발생하였으며 부정배로 발육될 시원세포들은 매우 큰 핵과 세포질로 충만되어 있고 주로 배낭근처에 있는 주공측의 주심조직에서 발생되었다. 기내배양 조건에서는 자연조건에서 보다도 훨씬 많은 부정배들이 배낭내에서 관찰되었으며 이러한 부정배들은 대부분 배낭과 밀접해 있는 주심세포층으로부터 발생하였다. 또한 몇몇 부정배들은 주심조직에서 직접 발생하는 것이 관찰되었다. Adventive embryo usually occurs inside the embryos ac nucellar tissue in the in Vivo state. Initial cells to be developed in to adventive embryos were conspicuous with large nucleus and dense cytoplasm, and arose mainly from nucellar tissue or from integuments. In the in Vitro culture, much more embryos were observed in the embryo sac. than in the in Vivo conditions, and embryos seemed to arise from the nucellar cell layer lining the embryo sac. Some of the adventive embryos were observed occurring directly from the nucellar.

The purpose of this study was to examine behavioral types of efficient soccer coaches by identifying relationship between athletic satisfaction and leadership behavior types of high school soccer coaches. who have an impact on soccer players. The study also took a closer look at the types of leadership behavior shown by soccer players depending on their school level, position and status-whether or not a key player or a bench warmer. A total of 287 high school soccer players were subjected to the study and the Leadership Scale for Sport (LSS) and the Satisfaction Scale for Soccer Players were used to obtain the study results. In terms of leadership behavioral type by school level. good schools were found to hold higher levels of perception on instruction behavior. autocratic behavior. democratic behavior and social support behavior than the relatively poor schools. No significant difference was found in terms of leadership behavior type by position. However, the analysis on the leadership behavior type by players status showed that the key players had a higher perception on instruction and training behaviors than the bench warmers. According to the athletic satisfaction by school level, no significant difference was found in sub-variables. The same was true for both athletic satisfaction by position and athletic satisfaction by players status. In terms of correlation between the leadership behavior type and athletic satisfaction, training and instruction behavior. democratic behavior, social support behavior and positive feedback behavior were found to have a significant correlation with the sub-variables of athletic satisfaction, which are, sport performance satisfaction and psychological satisfaction. Moreover, the leadership behavior type, training and instruction behavior and autocratic behavior were identified as variables that have a significant impact on sport performance satisfaction and psychological satisfaction, which are sub-factors of athletic satisfaction.

국내 다기관에서 조사한 지역사회획득 메티실린내성 황색포도알균의 빈도와 임상적 특성

목적 : 최근 전세계적으로 지역사회획득 메티실린내성 황색포도알균(community-associated methicillin-resistant Staphylococcus aureus, CA-MRSA)의 보고가 증가하고 있다. 하지만, 우리나라에서는 CA-MRSA 감염증에 대한 증례보고만 있을 뿐 아직까지 체계적인 연구결과가 없는 실정이다. 저자들은 국내에서 CA-MRSA의 빈도, 감염증의 임상적 양상, 분리된 균주의 항균제내성 양상을 조사하였다. 재료 및 방법 : 2005년 1월부터 2005년 6월까지 7개 병원에서 MRSA가 분리된 환자의 명단을 파악한 후 의무기록지와 건강보험심사평가원의 자료를 검토하였다. 외래나 응급실에서 혹은 입원 후 72시간 이내에 균주가 분리되고 MRSA 획득과 관련된 위험인자가 없는 경우 CA-MRSA로 정의하였으며, 분리된 균주의 임상적 의미에 따라 원인병원체(pathogen), 집락화(colonizer), 미결정(undetermined)으로 분류하였다. Penicillin과 oxacillin을 제외하고 3개 이상의 다른 계열 항균제에 내성이면 다제내성으로 정의하였다. 결과 : 연구기간동안 총 3,251주의 황색포도알균이 분리되었으며, 이 중 MRSA는 1,900주(58.4%)였다. MRSA 가운데 CA-MRSA는 114주(6.0%) 였으며, 이들이 분리된 부위는 귀(62주), 비뇨기계(14주), 피부 및 연부조직(11주), 호흡기계(10주), 혈액(3주) 등이었다. CA-MRSA 균주 가운데 집락균은 22주, 원인병원체는 22주였으며, 나머지 균주에 대해서는 그 임상적 의미를 결정할 수 없었다. 항균제 감수성 검사를 시행한 73균주 중 47주(64.4%)는 다제내성이었다. CA-MRSA 감염증 22예 중 피부 및 연부조직 감염(9예)과 중이염/외이도염(9예)이 가장 흔하였다. 침습적 감염증(invasive infection)은 4명(원발성 균혈증 3예, 감염성 관절염 1예)에서 확인되었지만, CA-MRSA 감염증으로 사망한 환자는 없었다. 결론 : 병원내 감염증에서는 MRSA가 심각한 문제이지만, 아직까지 지역사회 감염증에서 CA-MRSA는 흔하지 않았다. Background : Methicillin-resistant Staphylococcus aureus (MRSA) infection has emerged in patients who do not have the established risk factors. In Korea, little is known about the epidemiology and clinical features of community-associated MRSA (CA-MRSA). Material and Methods : Clinical microbiology laboratory databases of 7 hospitals were reviewed to identify the patients from whom MRSA was isolated during the period of January to July 2005. Only one isolate per patient was enrolled. In order to identify the risk factors of MRSA acquisition, the medical records and the Health Insurance Review Agency databases were reviewed. CA-MRSA was defined as MRSA isolated from patient without established risk factors. We analyzed patient demographics, underlying medical conditions, characteristics of infection, and antimicrobial susceptibility profiles. Results : Of total 3,251 S. aureus isolates, 1900 (58.4%) were MRSAs. Of the MRSA isolates, 114 (6.0%) were CA-MRSA. Of 114 CA-MRSA isolates, 22 (19.3%) were colonizers, 22 (19.3%) were pathogens, and the clinical significance of remaining 70 (61.4%) could not be determined. Median age of the 22 patients with CA-MRSA disease was 47 years. Nine patients had skin and soft tissue infections, 9 ear infections, 3 bacteremia, 1 septic arthritis. Seven patients had underlying medical disease. None died of the CA-MRSA infections. Of the 73 isolates of CA-MRSA, 47 (64.4%) were resistant to more than 3 classes of antibiotics besides β-lactams. Conclusion : Although MRSA is highly prevalent among hospital-associated S. aureus infection, CA-MRSA infections are not common.

A successful therapy of community-acquired pneumonia requires appropriate empirical antimicrobial therapy. Etiology and antimicrobial susceptibility of major pathogens of pneumonia can differ by country. Therefore, an ideal treatment guideline of community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia in immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.
